I've been reading all the post on chiari and wondered if anyone has a good out come of the surgery. I have been to 4 neurologist and 1 surgeon and keep getting different answers. 3 drs say I don't need surgery and the last one said that i really need it or could be paralyzed by any straining. I have a headache all the time and can barely function. Balance problems, numbness and burning in my hands and legs My hurn. Is only 5mm. Any advise? Thank you.
